| titleOfInvention | A kind of method of solvent-free preparing o-chloroaniline by catalytic hydrogenation |
| abstract | The invention belongs to technical field of fine, relate to the method for the solvent-free preparing o-chloroaniline by catalytic hydrogenation of ortho-nitrochlorobenzene.Take ortho-nitrochlorobenzene as raw material, in the presence of a catalyst, with hydrogen reaction under 70 DEG C ~ 120 DEG C and 0.5MPa ~ 5.0MPa pressure, reaction terminates aftertreatment and obtains Ortho-Chloro aniline.The method of the invention does not add solvent, overcome the defect adding solvent, avoid the problem of solvent environmental pollution and solvent recuperation, reduce facility investment, reduce production cost, adopt the inventive method that the transformation efficiency of ortho-nitrochlorobenzene can be made to reach 100%, the selectivity of Ortho-Chloro aniline is greater than 99.2%, and dechlorination rate is less than 0.09%. |
